- added the name server that the response came from to the Net_DNS2_Packet_Response object
- added the socket type (TCP or UDP) that was used for the request.
- changed the internal socket logic to use a local define for SOCK_STREAM and SOCK_DGRAM rather than the one provied with the sockets library; this isn't available if you're not using the library.
- fixed a bug when an AXFR fails; rather than returning right away, it was waiting until there was a timeout condition. Now it returns right away on failure.
